RUNUSER(1) User Commands RUNUSER(1)

NAME

runuser - run a shell with substitute user and group IDs

SYNOPSIS

runuser [OPTION]... [-] [USER [ARG]...]

DESCRIPTION

Change the effective user id and group id to that of USER. Only session PAM hooks are run, and there is no password prompt. This command is useful only when run as the root user. If run as a non-root user without privilege to set user ID, the command will fail as the binary is not setuid. As runuser doesn't run auth and account PAM hooks, it runs with lower overhead than su.

-, -l, --login
make the shell a login shell, uses runuser-l PAM file instead of default one, clears all envvars except for TERM, initializes HOME, SHELL, USER, LOGNAME and PATH
specify the primary group
specify a supplemental group
pass a single COMMAND to the shell with -c
pass a single COMMAND to the shell with -c and do not create a new session
pass -f to the shell (for csh or tcsh)
do not reset HOME, SHELL, USER, LOGNAME environment variables
same as -m
run SHELL if /etc/shells allows it
display this help and exit
output version information and exit

A mere - implies -l. If USER not given, assume root.
